In the meanwhile Arundel was ruining himself with ostentatious expenditure; borrowing vast sums of money from Italian bankers and scattering gifts of jewels of great value amongst the las who surrounded the Queen. He was a man far into middle age at the time, with two married daughters, the Duchess of Norfolk and Lady Lumley, and was in antiquity of descent the first of English nobles; but one can imag

橡套電纜MYP-0.66/1.14KV 3*35+1*16
(1) MYP礦用電纜絕緣屏蔽層,絕緣屏蔽層有三項(xiàng)基本功能
絕緣導(dǎo)體對地形成固定均勻電容,從而產(chǎn)生均勻波阻抗,使電纜線路內(nèi)的電壓波反射減到少。
使絕緣內(nèi)部電場徑向分布,從實(shí)用觀點(diǎn)看,也消除了絕緣表面的切向電場和縱向電場。
靈敏顯示絕緣狀態(tài),減少觸電危險(xiǎn),絕緣層表面到處與導(dǎo)電屏蔽層的電位相等,可以通過監(jiān)視導(dǎo)體與屏蔽層之間絕緣電阻的方法,顯示絕緣狀態(tài),當(dāng)任何一處絕緣電阻低于規(guī)定值時(shí),保護(hù)裝置動作,切斷電源,防止人身觸電事故發(fā)生。
(2) MY礦用電纜地線芯,煤礦的供電系統(tǒng)的中性點(diǎn)不是直接接地的,電纜的地線芯直流電阻必須滿橡套電纜MYP-0.66/1.14KV 3*35+1*16足有關(guān)規(guī)程規(guī)定,6KV供電系統(tǒng)中保護(hù)裝置的應(yīng)用不如低壓系統(tǒng)的普遍,電纜單相接地之后,往往不能及時(shí)處理,會引起另一向在不同區(qū)域?qū)Φ負(fù)舸?,造成兩相通過地線短路。因此,要求地線芯有足夠截面,地線芯與動力線芯之間存在電容和互感,在實(shí)際應(yīng)用中,地線芯必須良好接地,否則會引起嚴(yán)重的人身傷亡。
(3)MYPTJ礦用電纜監(jiān)視線(層),監(jiān)視線的主要功能是監(jiān)視地線的連續(xù)性,經(jīng)過結(jié)構(gòu)設(shè)計(jì)上的演繹之后,監(jiān)視線均布電纜軸心的同心圓周上,它又兼有監(jiān)視外界破壞物體侵入的作用。
(4)MC礦用電纜外護(hù)套,由于科學(xué)技術(shù)的進(jìn)步,使得彩色鮮艷的外護(hù)套工業(yè)化生產(chǎn)成為現(xiàn)實(shí),井下電線電纜橡套電纜MYP-0.66/1.14KV 3*35+1*16為便于區(qū)分電壓等級,規(guī)定6KV電纜外護(hù)層為紅色,1140V為黃色,660V及以下為黑色,這既便于區(qū)分不同電壓等級的電纜,又美化了煤礦井下的生產(chǎn)環(huán)境,至于露天礦用電纜,目前尚不能使用彩色護(hù)套,這是由于白色無機(jī)填加劑,在日光暴露初期,對光的折射,聚合物降解速度轉(zhuǎn)慢,經(jīng)過一段時(shí)間之后,氧化反應(yīng)終破壞了聚合物分子鏈,導(dǎo)致護(hù)套表面粉化和裂紋,所以,目前的露天電纜外護(hù)套仍以黑色為主。
礦用阻燃橡套電纜特點(diǎn):
1:移動頻繁。工作中需要經(jīng)常移動,要求護(hù)套有較好的耐磨性。電鉆電纜除經(jīng)常搬運(yùn)電鉆而拖橡套電纜MYP-0.66/1.14KV 3*35+1*16動,要求一定的抗拉力。采掘機(jī)電纜在工作中不斷在機(jī)組上卷放、收繞井在地面上拖動。
2:經(jīng)常彎曲和扭轉(zhuǎn).以電鉆電纜和采掘機(jī)電纜為嚴(yán)重。特別是電纜與電鉆或采掘機(jī)連接出,是受到彎曲、扭轉(zhuǎn)力以及拉力嚴(yán)重的部位。要求電纜在很好的柔軟性和耐多次彎曲、扭轉(zhuǎn)性。橡套電纜MYP-0.66/1.14KV 3*35+1*16
3:機(jī)械外力破壞。菜采區(qū)工作的電纜,易被掉下的礦石或是巖石的沖砸而損壞,或被大的礦石及其他裝備(如礦車)、材料壓住,壓扁電纜而引起電氣短路。在礦井電纜事故中,比率大。
